DESCRIPTION

v.net.alloc allocates subnets for nearest centres (direction from
centre). Centre node must be opened (costs >= 0). Costs of centre node
are used in calculation. Supported are cost assignments for both arcs
and nodes, and also different in both directions of a vector line. For
areas cost will be calculated along boundary lines.

NOTES

Center nodes have to be assigned to vector nodes using v.digit or added
from other map(s). Nodes and arcs can be closed using cost = -1.
